  * The base class for KDirStat application windows. It sets up the main window

  * statusbar. An instance of KDirStatView creates your center view, which is
  * connected to the window's Doc object.  KDirStatApp reimplements the methods
  * that TDEMainWindow provides for main window handling and supports full
  * session management as well as using TDEActions.
